California homeowners forced to rebuild because of a wildfire won't have to install solar panels under a new law signed Friday, Sept. 6, 2019, by Gov. Gavin Newsom. New rules taking effect Jan. 1, 2020, make California the first state in the county to require solar panels on new homes. (AP Photo/Rich Pedroncelli, File)
